Contains components that help with OpenEBS data engine upgrades

Below are the steps for upgrading the OpenEBS reources:

Note:

  • If current version of ndm-operator is 1.12.0 or below and using virtual disks as blockdevices for provisioning cStor pool please refer this doc before proceeding.
  • After upgrading the cStor or Jiva control plane, you have to upgrade Jiva/cStor pools and volumes to the latest control plane version as early as possible. While Jiva/cStor pools and volumes will continue to work, the management operations like Ongoing Pool/Volume Provisioning, Volume Expansion, Volume Replica Migration, cStor Pool Scaleup/Scaledown, cStor VolumeReplica Scaling, cStor Pool Expansion will not be supported due to difference in control plane and pools/volumes version.

Below are the steps for migrating the OpenEBS cStor custom reources:

Note:

  • If the Kubernetes cluster is on rancher and iscsi is running inside the kubelet container then it is mandatory to install iscsi service on the nodes and add extra binds to the kubelet container as mentioned here.
  • Minimum version of Kubernetes to migrate to CSPC pools / CSI volumes is 1.17.0.
  • If using virtual disks as blockdevices for provisioning cStorpool please refer this doc before proceeding.
